e. Open main door. The dryer
must stop
and
ALL
output indicator lights on the back side of the
microprocessor (computer) board
must go out
. (Refer to illustration on
previous page
[
page 57
].)
f.
Try to restart the dryer with the main door open.
g. The microprocessor (computer) board's L.E.D. display
must read
"
DOOR
."
h. Close the main door and restart the dryer.
i. Functional check of microprocessor (computer) board is complete
.
2. Direct Spark Ignition (DSI) System
a. Upon completing installation of the replacement
Direct Spark Ignition (DSI) module, reestablish
power to the dryer.
b. Start the drying cycle.
c. The ignition (DSI) module's L.E.D. indicator will
light "
red
" for up to approximately 1.5 seconds (pre-
purge time).
d. The module's indicator light will then turn "
green
."
The gas valve will be energized and the ignitor probe
will spark for approximately 8 seconds. The burner
flame
should now be
established.
e. With the burner flame on, remove the flame sensor
wire from the FS terminal of the DSI module.
f. The burner flame
must shut off
and the ignition
module
must lock out
with the DSI module's
indicator light "
red
."
g. Stop the drying cycle, with the flame sensor wire
still removed, restart the drying cycle.
h. The ignition module
must proceed
through the
pre-purge, with the indicator light "
red
," the ignition
trial time of approximately 8 seconds, with the
indicator light "
green
," and then proceed to lock out
with the indicator light "red".
i. Functional check of the Direct Spark Ignition (DSI) Module is complete.
1) Replace the flame sensor wire from the FS terminal to the DSI module.
